Re: HELP: Segmentation Fault!

hi Pathmenanthan,
I guess the prg causes a segfault, right ?

To locate the error you need:
1. mail the maintainer about the problem perhaps he know it already
and idependently:
2. recompile the prg with option -g (compiler leaves debuginformation in the code)
3. run the code until it crashes

use gdb <prg> core
the find the offending line.


alternatively you can run the programm directly in the debugger.

A sudden crash after some time hints for me to an overrunning array,
look out for possible bufferoverflows and not iniliased variables.

HINT: enabling debugmode may work also

BEWARE: The -g option causes a huge grow in programm size don be afraid but
it may also take longer to crash because there is more nonvitol information
to crash. DONT thing it solves a problem when the programm dont crash when
compiled with -g !
